Growing crime rates over the past 30 years don’t explain the skyrocketing numbers of black — and increasingly brown — men caught in America’s prison system, according to Alexander, who clerked for Supreme Court Justice Harry Blackmun after attending Stanford Law. “In fact, crime rates have fluctuated over the years and are now at historical lows.”

“Most of that increase is due to the War on Drugs, a war waged almost exclusively in poor communities of color,” she said, even though studies have shown that whites use and sell illegal drugs at rates equal to or above blacks. In some black inner-city communities, four of five black youth can expect to be caught up in the criminal justice system during their lifetimes.
